When it comes to building a charming garden shed or adding a rustic touch to your timber frame home, choosing the right cladding is crucial. If you're wavering between shiplap and log lap cladding, you're not alone. Both types offer unique aesthetics and functional benefits. Let’s dive into their differences and strengths to help guide your decision.
Timber Framing: A Timeless Construction Method
Before we delve into the cladding options, it's essential to grasp the basics of timber framing. Unlike other construction methods, timber framing showcases wooden beams which form the skeleton of a building. This method is prized for its durability and natural aesthetic, making it a perfect match for both shiplap and log lap cladding.
What is Shiplap?

Shiplap is a type of wooden board traditionally used in the construction of sheds, barns, and outbuildings. Characterised by a rabbet or notch cut into the top and bottom of each board, these overlaps create a tight seal which is excellent for weatherproofing.
Key specs to bear in mind:
-
Material: Various woods are used, such as pine or cedar.
-
Treatment: Often treated, or tanalised, to withstand moisture and insects. Check our 16x100 Tanalised Treated Shiplap here.
Advantages of Shiplap
-
Weather Resistant: Shiplap's overlapping design provides excellent protection against wind and rain.
-
Aesthetic Appeal: Its flat profile with subtle grooves suits both modern and traditional styles.
-
Easy to Install: Each board interlocks precisely, making DIY projects straightforward.
Exploring Log Lap Cladding

Log lap cladding mimics the appearance of rounded logs, giving structures a rustic log cabin look. It's perfect if you're aiming for that warm, country vibe.
Essential specs include:
-
Material: Can be sourced from sustainably-grown timber.
-
Size: Often larger than shiplap; explore our 32x125 Tanalised Treated Loglap Cladding here.
Benefits of Log Lap Cladding
-
Insulation Highlight: Due to its thickness and rounded shape, it inherently offers better insulation properties.
-
Aesthetic Warmth: Provides a traditional log cabin feel suitable for outdoor retreats or summerhouses.
-
Durability: Often manufactured from robust, treated timber to ensure longevity against the elements.
Comparing Installation Processes
Both shiplap and log lap cladding are designed for straightforward installation. However, it’s crucial to ensure a firm timber frame or OSB board base for attaching the cladding.
-
Shiplap Installation: The interlocking design makes it a favourite among DIY enthusiasts.
-
Log Lap Installation: Slightly more complex due to the rounded edges but equally rewarding with a rewarding finish.
Roofing Considerations: Roof Shingles and Roof Felt
Your choice of cladding impacts not just the walls but also how you might want to finish the roof to ensure uniformity and protection. Here’s what to consider:
-
Roof Shingles: Ideal for a shiplap aesthetic. They come in various styles and add a polished look.
-
Roofing Felt: A versatile choice, roofing felt offers additional insulation and moisture protection. Perfect for any cladding type, including log lap.

Multifunctional OSB and Plywood

When preparing the underlying structure, both OSB Board and Plywood are excellent choices. They provide a robust surface to which cladding can be securely attached.
These materials enhance structural integrity and can be treated for added resilience.
Making Your Decision: Who Should Use Each Cladding?
-
Choose Shiplap if: You prefer a modern touch with a minimalist finish. Ideal for garden sheds or contemporary designs.
-
Opt for Log Lap if: You love the rustic, log cabin aesthetic. Perfect for summerhouses or rural settings where insulation is key.
Conclusion
Choosing between shiplap and log lap cladding isn’t just about aesthetics; it’s about functionality, design integrity, and your project’s goals. Whether you're DIY-ing a garden shed or looking to accentuate a timber frame home, each cladding style offers unique benefits that can transform spaces elegantly.
